[0029] Among them, traction assembly includes strip-shaped hole 313 being equipped in the surface of one side of support plate 302, strip-shaped hole 313 is equipped along the height of support plate 302, the inner cavity of strip-shaped hole 313 is slidably connected with connecting block 304, the both sides of connecting block 304 are respectively provided with connecting strip 306, the both ends of two connecting strips 306 are respectively connected to the end of corresponding side flow guide plate 301 and the corresponding side surface of connecting block 304 through rotating piece, the bottom of hollow disc 100 is provided with pulling assembly for pulling connecting block 304 downwards to adjust the opening angle of flow guide plate 301, by the setting of traction assembly, connecting strip 306 pulls the end of flow guide plate 301, when airflow impacts flow guide plate 301, connecting strip 306 can share a part of impact force, so that the pressure borne by flow guide plate 301 is relieved to a certain extent, the overall impact resistance of flow guide plate 301 is enhanced, and the angle of flow guide plate 301 is adjusted, so that airflow impacts flow guide plate 301 at a more suitable angle, reduces the adverse forces such as lateral force of airflow on flow guide plate 301, thereby improving the ability of flow guide plate 301 to withstand airflow impact.

[0030] The pulling assembly includes a movable disk 104 located below the hollow disk 100. A drive motor 200 is embedded in the bottom of the hollow disk 100. The output shaft of the drive motor 200 is keyed to a lead screw 201. A nut seat 202 is threaded onto the surface of the lead screw 201 and is fixedly embedded in the middle of the movable disk 104. Push rods 303 are fixedly connected to the bottom of several sets of connecting blocks 304. The ends of the push rods 303 are sealed downwards, penetrate the hollow disk 100, and are fixedly connected to the movable disk 104. On the top surface, by setting the pull assembly, the drive motor 200 drives the lead screw 201 to rotate, thereby causing the nut seat 202 to move on the lead screw 201, which in turn drives the moving disk 104 and the push rod 303 to move up and down, thereby driving the connecting block 304 to move up and down in the strip hole 313, thereby adjusting the angle of the guide plate 301. At the same time, the motor drive can achieve precise speed and rotation angle control, thereby accurately adjusting the opening and closing angle of the guide plate 301 to meet the precise requirements of gas guiding under different working conditions.

[0031] The drive motor 200 can be selected from, but is not limited to, a Siemens SIMOTICS S-1FK7 series waterproof servo motor.

[0032] Among them, the bottom of both sides of the hollow disk 100 is fixedly connected with limit rods 102. The two sets of limit rods 102 slide through the moving disk 104 respectively. With the setting of the limit rods 102, during the up and down movement of the moving disk 104, the limit rods 102 can prevent the moving disk 104 from shaking or deviating, ensuring that the moving disk 104 can only move smoothly in the up and down direction, thereby ensuring the stability and accuracy of the movement of the connecting block 304, and thus improving the accuracy and reliability of the angle adjustment of the guide plate 301.

[0033] The rotating component includes connecting shafts 307 fixedly connected to both ends of the connecting bar 306. Each end of the connecting shaft 307 is rotatably fitted with a connecting sleeve 308. The connecting sleeves 308 located at both ends of the connecting bar 306 are fixedly connected to the ends of the corresponding side guide plates 301 and the corresponding side surfaces of the connecting block 304. By setting the rotating component, the connecting bar 306, the ends of the guide plates 301, and the connecting block 304 can achieve flexible rotational connection, which can smoothly transmit force and ensure that the guide plates 301 can flexibly rotate around the connecting rod 311 when the connecting block 304 moves, thereby adjusting the angle and reducing friction and resistance during rotation.

[0034] The fixing connector includes fixing plates 101 fixedly installed on the bottom of both sides of the hollow disk 100. Each of the two sets of fixing plates 101 is threaded with a fixing bolt 103 on the opposite side. The two sets of fixing bolts 103 are threaded through the fixing plates 101 and threaded to the inner wall of the packing tower. By setting the fixing connector, the fixing bolts 103 are threaded through the fixing plates 101 and connected to the inner wall of the packing tower, which can firmly fix the device inside the packing tower. It has high stability and reliability, and can withstand various forces and vibrations generated by the device during operation, ensuring that the device will not loosen or shift during long-term operation.

[0035] Guide bars 305 are fixedly connected to both the front and rear sides of the connecting block 304. Guide grooves 312 are provided on the inner walls of both sides of the strip hole 313 along the height direction. The surfaces of the two sets of guide bars 305 are slidably connected to the inner cavities of the corresponding side guide grooves 312. Through the setting of guide grooves 312 and guide bars 305, the movement direction of the connecting block 304 can be restricted, preventing the connecting block 304 from deviating or shaking during the sliding process, ensuring that the connecting block 304 can move smoothly along the height direction of the strip hole 313, thereby ensuring the accuracy and stability of the angle adjustment of the guide plate 301.

[0036] The bottom of the guide plate 301 is provided with several sets of guide grooves 309. By setting the guide grooves 309, the flow path of the gas can be further refined, so that the gas can be more evenly distributed and guided when passing through the guide plate 301. At the same time, the guide grooves 309 can change the flow state of the gas, increase the contact area between the gas and the surrounding environment, and improve the efficiency of mass transfer, heat transfer and other processes of the gas in the packed tower.

[0037] Working principle;

[0038] First, the fixing plates 101 at the bottom of both sides of the hollow plate 100 are threaded to the inner wall of the packed tower using fixing bolts 103, thereby securing the entire device inside the packed tower and ensuring that the device will not shake or shift during operation.

[0039] Based on the actual working conditions inside the packed tower and the contact effect with the packing, determine whether it is necessary to adjust the opening and closing angle of the guide plate 301.

[0040] If the angle of the guide plate 301 needs to be adjusted, start the drive motor 200 embedded in the bottom of the hollow disk 100. The output shaft of the drive motor 200 drives the lead screw 201 to rotate. Since the lead screw 201 is threaded with a nut seat 202 and the nut seat 202 is fixedly embedded in the middle of the moving disk 104, the nut seat 202 will move up and down on the lead screw 201 as the lead screw 201 rotates, thereby driving the moving disk 104 to move up and down.

[0041] When the moving disk 104 moves up and down, the push rod 303, which is fixedly connected to the bottom of the connecting block 304, moves together with the moving disk 104. This causes the connecting block 304 to slide up and down in the strip hole 313 on one side surface of the support plate 302. The connecting strip 306 moves one end of the guide plate 301 up or down, so that the other end of the guide plate 301 rotates along the connecting rod 311, thereby changing the angle of the guide plate 301. This allows for adjustment of the opening and closing angle of the guide plate 301 and prevents the gas flow rate from being too high and impacting the guide plate 301, which could damage the guide plate 301. At the same time, it allows the gas to flow at a new angle, achieving better gas distribution and contact with the packing.

[0042] Furthermore, during the adjustment process, the limiting rods 102 at the bottom of both sides of the hollow disk 100 slide through the moving disk 104 to restrict the movement direction of the moving disk 104, ensuring that the entire angle adjustment process is stable and reliable, avoiding shaking or deviation, and ensuring the accuracy of the angle adjustment of the guide plate 301.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
